In semen evaluation, which term refers to the shape of the sperm cell?

• A. Morphology
• B. Motility
• C. Viability
• D. Volume

Answer: (A)

Shape and structural features of spermatozoa are described by morphology. In semen evaluation, morphology means looking at the sperm under a microscope to judge the form of the head, midpiece, and tail and identify abnormalities. These structural traits influence the sperm’s ability to fertilize an egg, so morphology specifically captures the aspect of “shape.” Motility measures movement, viability is whether the cells are alive, and volume is the amount of semen collected. Therefore, morphology is the term that refers to the shape of the sperm cell.
